Radiator structure and production method thereof

Abstract

Disclosed are a radiator structure and a production method thereof. A radiator comprises a body and a plurality of radiating fins. The body is provided with a first end and a second end with the lengthwise direction defined therebetween. The radiating fins are arranged in a forming die, the body is enabled to be pushed into the forming die at a high speed in a machining mode, and bending sections of the radiating fins in the forming die facing toward the body are forced into combined slots from the first end and move along the lengthwise direction to the second end to be combined on the surface of the body.

Description

technical field [0001] The invention relates to a radiator structure and its manufacturing method, especially to an annular radiator structure and its manufacturing method. Background technique [0002] The known cylindrical radiator includes a cylinder and a plurality of fins connected to the surrounding surface of the cylinder. The known technology discloses the connection method between the fins and the surrounding surface of the cylinder as follows: [0003] 1. The case of patent application No. 098105429 in Taiwan, China discloses a method for planting and tightening tubular radiator fins and its application device, which mainly includes: a motor driven by a power source to generate step-by-step rotation Die base; provide a cylinder, the cylinder is positioned on the mold base, and the surrounding surface of the cylinder is provided with many grooves; provide a fin group, including a plurality of fins, and the fin group is set on one end side of the mold base , when th...

[0004] 2. The case of patent application No. 098220381 in Taiwan, China discloses a heat dissipation structure with combined heat dissipation fins, which mainly includes a metal base and a plurality of heat dissipation fins, and the heat dissipation fins are integrally stamped from a metal plate The fins are bent into a U shape. The heat dissipation fins include two heat dissipation parts and an elastic buckle part. The two heat dissipation parts are respectively in the shape of a flat plate. The elastic buckle part is U-shaped. The end has reset elasticity, and its two ends are fixedly connected to one end of the heat dissipation part respectively. The two ends of the elastic buckle can be pressed and close to each other, so that the elastic buckle is deformed, so that the elastic buckle The buckle can be inserted into a plurality of grooves recessed in the metal base body, and the grooves are equivalent to the shape of the elastic buckle, which presents a shape in which the opening shrinks, so that the outer surface of the elastic buckle can be reset by it It is elastically fastened to the groove surface of the metal base to insert all the heat dissipation fins into the metal base and form a heat sink. Compared with its products, the production time of the groove is long, and the heat dissipation fins and the metal base cannot be completely tightly matched. If the heat dissipation fins are easily separated from the two ends of the metal base by external force or longitudinal thrust, the known technology has The following disadvantages:

[0006] 2. It cannot be completely tightly matched, and the cooling fins are easy to detach due to external force or longitudinal thrust
